findedge — Find the index of an edge between two nodes.
findedge(G,s,t) returns the one-based edge index for the first matching edge, or 0 when no edge exists.
Syntax
findedge(G,s,t)Using findedge with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how findedge changes the result.
Run a small findedge example, explain the result, then change one input and compare the output.
